I have being calling for years to do a branch line off the Milton Line to Sq On from both ends using EMU's assuming CP will agreed to EMU's. The tunnel will have to start north of Dundas from the south and north of the 403. The City needs a new transit Hub to handle 150,000 riders by 2040. There will be no service to Cooksville for this branch line and will be a different GO Service.
I have stated for over 10 years to council that the Mall is the white elephant in trying to create a downtown and the city has said the same thing. The mall needs to shrink to 1/5 of its size on a number of floors with development on top of it.
I have also stated of seeing 200-300,000 people living and working in this area and the 18,000 units doesn't cut it.
Do the math; if 37 towers are to be built, 7 will be office towers and this leaves 30 towers to hold 18,000 units. Other than a few tall towers, the rest will be midrise only. The city wants green space and a better grid system than what there is there today.
Oxford has already has been given permission to reduce parking standards for all its lands and it needs to fall more as the area will never support all the car traffic there and will be gridlock on Boxing day and other major events with transit being really screw.
